Genes affected

DNAH11 (HGNC:2942): (dynein axonemal heavy chain 11) This gene encodes a ciliary outer dynein arm protein and is a member of the dynein heavy chain family. It is a microtubule-dependent motor ATPase and has been reported to be involved in the movement of respiratory cilia. Mutations in this gene have been implicated in causing Kartagener Syndrome (a combination of situs inversus totalis and Primary Ciliary Dyskinesia (PCD), also called Immotile Cilia Syndrome 1 (ICS1)) and male sterility.

Uncertain significance, criteria provided, single submitter	clinical testing	UNC Molecular Genetics Laboratory, University of North Carolina at Chapel Hill	Oct 31, 2018	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Sep 24, 2021	This sequence change replaces arginine with histidine at codon 4437 of the DNAH11 protein (p.Arg4437His). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs775606157, ExAC 0.005%). This variant has been observed in individual(s) with clinical features of primary ciliary dyskinesia (Invitae). ClinVar contains an entry for this variant (Variation ID: 977532). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DNAH11 protein function. This variant disrupts the p.Arg4437 amino acid residue in DNAH11. Other variant(s) that disrupt this residue have been observed in individuals with DNAH11-related conditions (PMID: 24450482; Invitae), which suggests that this may be a clinically significant amino acid residue. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Aug 30, 2016	The p.R4437H variant (also known as c.13310G>A), located in coding exon 82 of the DNAH11 gene, results from a G to A substitution at nucleotide position 13310. The arginine at codon 4437 is replaced by histidine, an amino acid with highly similar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 5973 samples (11946 alleles) with coverage at this position. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
